On a rather older seedling, two young leaves stood at noon at 55° above the horizon, and at night at 86°, so each had risen 31°. The angle, however, was less in some cases. Similar observations were occasionally made on young leaves (for the older ones moved very little) produced by nearly full-grown plants. Batalin says (‘Flora,’ Oct. 1st, 1873, p. 437) that the young leaves of Stellaria close up so completely at night that they form together great buds.
